This example contains valid Rust syntax.
But, I currently struggle for the linking process, it failed using cargo xbuild.

I believe you need to create .cargo/config, build.rs and memory.x. See esp32-hal as a reference.

fix release linking process

The "crt1-sim.so and _vectors.so not found" error resolved.
But, the CIF not supported on debug build still appeared.

Thanks @jessebraham, the missing files helped, but only for release build.

$ rustup run xtensa cargo xbuild --target=xtensa-esp8266-none-elf --example blinky --release

When building for debug mode, it stopped on " CFI is not supported for this target" error. Maybe related to espressif/llvm-project#6.
